EGG-TESTER.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed March 19, 1910. SerialvNo. 550,435.

To all whom tt may concern:

Be it known that I, l/VILHELM SoHRoEDER, a citizen of the United States,residing at Berkeley, in the county of Alameda and State of California,have invented certain new and useful Improvements in Egg-Testers, ofwhich the following is a specification.

This invention relates to egg testers, and the principal object of thesame is to provide a novel lamp holder and a pair of cooperating mirrorswhich are adapted to reliect the light rays from a lamp on said holderto an egg receptacle, so that an egg in said receptacle may be tested ina short time.

In carrying out the object of the invention generally stated above itwill be understood, of course, that the essential features thereof arenecessarily susceptible of changes in details and structuralarrangements, one preferred and practical embodiment of which is shownin the accompanying drawings, wherein Figure 1 is a view in frontelevation of the improved tester. Fig. 2 is a central vertical sectionalview thereof taken on the line 2 2, Fig. 1, the lamp being shown inelevation. Fig. 3 is a View' in rear elevation, the lamp being omitted.

Referring to said drawing by numerals, 1 designates the flat andpreferably annular base of the improved tester, which has a handle 2 bymeans of which movement of the tester is facilitated. At one portion ofits periphery, the base is provided with an upright strip 3, preferablya wide strip of sheet metal. The upper end of strip 3 carries a mirrorhousing 4 through which a horizontal shaft 5 extends, said shaft beingjournaled in the side walls of said housing and one of its projectedends equipped with a handgrip 6 by means of which said shaft may bemanually rotated. A mirror 7 is mounted on shaft 5 within housing 4,said mirror being preferably concaved.

An egg receptacle 8 is seated on top of housing 4, the bottom of saidreceptable forming the top of said housing and being provided with anopening 9 that communi- Cates with said housing 4, said opening beingpreferably of an egg shape. Receptacle 8 is provided with doors 10-11which are hinged to its front surface, said doors only partly closingsaid front surface so that a central opening 12 is provided in the frontof the receptacle through which an egg seated in opening 9 may beviewed.

At a point on the periphery of base 1 opposite the strip 3, a verticalrod 13 projects from said base, said rod extending to a higher planethan housing 4- and having its upper -end 14 inwardly inclined andequipped with a mirror 15.

A lamp 16 is mounted on base 1 between strip 3 and supporting rod13, theglobe 17 of said lamp extending well above mirror 7, so that the lightrays therefrom will be reected downward by mirror 15 to mirror 7, and bereflected from the latter mirror to an egg seated in opening 9, therebypermitting an inspection of the egg to be made through sight opening 12.

It will be understood that mirror 7 is mounted on a rotatable shaft sothat its angle may be varied when desired, and also that the use of thedoors for the egg receptacle permits ready access to be had to saidreceptacle so that the handling of the eggs will be facilitated.

What I claim as my invention is 1. An egg tester comprising a base, asupport projecting from one side thereof, a mir- Vror housing at theupper end of said support, an inclined adjustable concaved mirrormounted therein, an egg receptacle mounted on the top of said housingand provided in the bottom with an egg seat communicating` with saidhousing and with a sight opening, a supporting rod projecting from theopposite side of said base, a mirror carried by the upper end thereof,and a lamp seated on said base between said supporting rod and saidmirror housing support.

2. An egg tester comprising a base, oppositely disposed supports carriedthereby, a mirror housing carried by one support, an adjustable mirrortherein, an egg receptacle carried by said housing and provided with anegg seat that communicates with said housing, said receptacle alsoprovided with a sight opening, and a reflector carried by the othersupport in a plane higher than said mirror.

3. An egg tester comprising a base, a support projecting from oneportion thereof, a mirror housing carried by the upper end of saidsupport, a shaft rotatable in said housing, a mirror on said shaft, anegg receptacle on said housing and having an egg seat in its bottom thatcommunicates with said housing, doors for saidreceptaele said doorsbeingV spaced apart to provide'a sight open-V ing, a rod projecting-froman-oppositepor; tion of said base and having an inwardly inf,

vertically arranged supporting rod projecting:- fnont onefpjortion'`thereof, a Vertieally arranged supporting strip projeetingifrom anopposite' portion of: saidl base, a; nleector j carried by the npper endof said rod, a 1nir-` ror housing carried by the upper end of saidstrip, a mirror therein, an egg receptacle 15 forming the top of saidhousing, and a i source of light adapted to be seated on said :basebetween the supporting rod and strip.

In testimony whereof I aiix my signature in presenceI of; two witnesses.
